Exam 33: The Plant Body

You have discovered a living fossilized plant that is a relative of magnolias and had been thought to be extinct for the past five million years.The plant has rounded leaves, aerial roots, and a woody trunk.From this information, you expect to find two _______ in the stem of the tree.

Facilities such as the Global Seed Vault in Norway, where seed samples from all parts of the world are stored for the future, are necessary for the preservation of genetic _______.

In which state would you be least likely to find distinct annual rings in eudicot tree trunks?

The shoot apical meristem is found _______ the nodes of mature leaves on the stem.

Photosynthesis takes place in the leaf tissue called _______.

Which of the following is not a stem?

The bulk of nonwoody root cells are _______ cells.

The complex carbon-containing compound known as lignin

Suppose you are studying tropical plants in a Costa Rican cloud forest and find a tree that is a eudicot in the forest ecosystem.This plant most likely has a(n) _______ root system.

A very strange mutant mustard plant makes no internodes, instead producing node, connected to node, connected to node, etc.This plant makes incomplete _______ of its stem, resulting in a very short plant.

Unlike tracheids, vessel elements

You are working with a mutant plant, and the cells in this plant adhere poorly to one another.You conclude that the mutation is due to a defect in the formation of

What kind of cells help to keep the transport cells of the phloem alive?

Which statement about leaves is false?

The term for the structure that emerges from a shoot apical meristem and eventually becomes a mature leaf is a(n)

Refer to the figure showing a plant periderm. The periderm, which is the outer layer of the secondary plant body, provides protection for interior tissues by keeping water in and pathogens out.What function is provided by structure A in the figure?

Plant cells that are photosynthetically active are parenchyma cells found in the _______ layer of the leaf.

An experimentally produced mutant plant in which the apical meristems were replaced with lateral meristems would be able to grow in girth but not in _______.

Primary plant growth, as compared to secondary plant growth, produces proportionally more

A newly discovered plant growing in a tropical forest has parallel veins in its leaves and pith in its roots.The location of the pith helps to determine whether this plant is a monocot or dicot because pith is found
